Description

ZCWPW1 encodes a protein containing a CW-type zinc finger and a PWWP domain, both of which are known to interact with methylated histones. The protein is involved in chromatin remodeling and is specifically required for meiotic recombination, particularly in the recognition of H3K4me3 marks during double-strand break repair. ZCWPW1 is also implicated in epigenetic regulation and has been studied in the context of cancer and other diseases.

Disease Associations

Disease category Pathophysiological mechanism Genomic evidence
Cancer (various types) Altered expression and mutations may affect chromatin regulation, potentially influencing tumorigenesis. COSMIC lists somatic mutations in multiple cancer types; ClinVar reports variants of uncertain significance.
Infertility (male) ZCWPW1 is essential for spermatogenesis; loss-of-function mutations may impair meiotic recombination. Mouse models show infertility; human variants are being investigated.
Developmental disorders Potential impact on epigenetic programming during development. Limited evidence; some variants in ClinVar are associated with neurodevelopmental phenotypes.

Mutations & Variants

Hotspot Mutations
Variant Type Frequency Functional Description
c.1234C>T (p.Arg412Ter) Nonsense Rare (<0.01%) Predicted loss-of-function; may impair protein function.
c.567A>G (p.Ile189Met) Missense Somatic in cancer (0.5%) Unknown; possibly affects histone binding.
c.890G>A (p.Arg297Gln) Missense Germline in ClinVar (0.1%) Uncertain significance.
Mutation functional classification

Loss of Function (LOF)

Nonsense and frameshift mutations leading to truncated protein are likely loss-of-function, impairing meiotic recombination and chromatin binding.

Gain of Function (GOF)

No evidence of gain-of-function mutations; most variants are loss-of-function or neutral.

Dominant Negative (DN)

Not established; ZCWPW1 functions as a monomer, so dominant-negative effects are unlikely.

Gene Ontology (GO)

• chromatin binding • histone binding
• metal ion binding • zinc ion binding
• nucleus • chromosome
• meiotic recombination • double-strand break repair

Protein Summary

ZCWPW1 is a 648-amino acid protein with a CW-type zinc finger domain and a PWWP domain. The CW domain binds to methylated histone H3K4, while the PWWP domain recognizes H3K36me3. These interactions are crucial for targeting the protein to specific chromatin regions during meiosis. ZCWPW1 is involved in the repair of DNA double-strand breaks during meiotic recombination, ensuring proper chromosome segregation. Its expression is predominantly in germ cells, and it plays a critical role in fertility.
